Proteins are biological polymers constructed from amino acids joined together to form peptides. These peptide subunits may bond with other peptides to form more complex structures. Multiple types of chemical bonds hold proteins together and bind them to other molecules. Take a closer look at the chemical bonds responsible for protein structure.
Photosynthesis creates glucose and oxygen. used for humans to inhale and then exhale carbon dioxide to go back into plants and redo this cycle.
